I believe the earlier round Nelson mufflers are available now . It is the oval ones that are not being produced by Nelson. I bought one from Rick Corder,Mo. a few years ago

I've got some dimensions from a 180/185 OEM muffler. Total overall height is 36 inches. A 15 inch tailpipe, a 3 inch inlet pipe and an 18 inch main body. The outlet pipe is 2 1/4" I.D. and the inlet pipe is 2 3/8" I.D.   I'll try and get a D-17 series 4 muffler measurement tomorrow. I do know for sure that the tailpipe on the S-3 and S-4 is smaller in diameter than the 170-175. I think it's 1 7/8" while the 170-175 are 2 inches.

The WD45 gas & diesel and early D17 Nelson mufflers are still available. This muffler (pn 229531) fits WD45 gas/diesel tractors and D17 gas tractor up to serial #24001. I sell this muffler for $135 + shipping. Like Pat said another member Rick Corder has them also. Rick is in Missouri, I am in Wisconsin, so Rick would be closer to you in KS.

Thanks for getting some original measurements Dr! I will add that to my notes! From my research I believe the original D17 outlet pipe is 7.75" long and has an O.D. of 1 5/8". The original 170/175 gas mufflers outlet pipe is 15 3/8" long and has an O.D of 1 7/8" (Thank you GreenOrange for 170 specs). Will wait to see if your measurements confirm the late D17 gas muffler sizes.

I don't have any D17d/D19 specs so if someone has those I will be interested to hear them. Would be awesome if D15d/D17d and D19gas/diesel were the same or similar, I could combine those into the same run of 100.

Alex, is that muffler for the WD45/D17 straight thru and blocked/baffled? Just wondering because I have seen them both ways just don't remember what brands they were.

I measured the D-17 S-4 I grew up on, and it is the same 18 inch oval body as a 180/185. The inlet is 2 1/2" tall and 2 inch O.D. and the offset outlet is 7 inches tall and 1 1/2" I.D. or 1 5/8" O.D. , which makes overall height 27.5 inches.

THE NELSON MUFFLERS ARE COMING!!!

I decided to go with mufflers for the late D17 gas tractors ser#42000+. These are the original style with offset outlet. The 3rd pic in JC(WI)'s post on the first page shows what these mufflers will look like. Dr Allis's post above states the dimensions. And, wait it gets better! My estimated price above was $200 per muffler, but these will be only $157 per muffler!!!!!!! :) I will post an add in the classifieds with more details for those who want these for their D17 gassers.

I would like to thank those who responded and voiced their opinions. Getting that input helped me to decide in what direction I will go with these mufflers. This run will be the D17 oval gas muffler only. If this goes well, I would like to order another Nelson muffler run for a different model tractor, perhaps the D15 or D17 diesel muffler or the 170/175 gas muffler (which is slightly different than this D17 one). Please give me your feedback on which Nelson muffler I should try next!

How difficult would it be to convert the sheet metal on a Series I and II D-17, to accept the oval muffler used on Series III & IV?

A true series 1 uses the same muffler as a WD45, so there is no pipe on the exhaust manifold for the oval muffler to slide on to. A true series 2 does have a pipe and the oval hole in the hood is all it should take. The oval muffler inlet is "on-center" so the marking out of the oval hole is easy.

I wouldn't. Would be like the guys blasting 10 inch holes in their diesel pick-up truck beds behind the cab to I "guess" look cool. Again, JMO. I must admit though, what is "wrong" with the available round muffler ??

The oval muffler was quieter than any round muffler with minimal to zero power loss. If you ran an oval muffler 8 hrs on a disc or a plow, you appreciated the benefit over the round muffler.

Our early 17 has an oval muffler. I'll ask dad if gramp cut the hole or who did. Guess the governor went screwy and over revved and broke crank. Both my gramp and great uncle aren't with us anymore so I can't ask how it exactly happened. It was back when allis was still, and gramp got a new engine from allis which made it a latter exhaust manifold.

Back to the original subject of this post, Great job by Alex convincing Nelson to produce another round of the elusive original D17 oval mufflers. One question for you Alex; I assume they will be painted black as were the originals?

Alex, what happened to your first diagram picture?

 Was kinda hoping the 170 would have been the chosen muffler and the height of the exhaust pipe could be cut off to desired length. But a fellow could slip another pipe over if he really wanted to get the ex. up higher.

Lonn, I wouldn't use a torch, that would warp the metal... but a plasma cutter would maybe do the job in a sweet order, providin the hand is steady. LOL

The 170/175 muffler outlet is not only longer, but it is larger in diameter over the D-17 S-3/4 muffler.

JC- I deleted my sketched drawings because I had used measurements off the stanley mufflers and they are not the same as the Nelson measurements.

Although I didn't choose the 170/175 gas muffler for this run, I am leaning toward ordering that one next, unless a different muffler would be in higher demand.
